In an electrolytic cell comprising parallel spaced anode and cathode electrodes and a membrane assembly dividing said cell into anode and cathode compartments, the membrane assembly includes a cation permselective membrane and a protective cloth of woven, knitted or felted fabric positioned between the membrane and the anode or the cathode or in both positions. As shown membrane leaves 34 and 40 are positioned between anode leaf 20, an intermediate leaf 24 comprising cathode 26 and anode 28, and a cathode end leaf 30. Anolyte from tank 46 is circulated in parallel through the anode compartments by means of pump 44, and catholyte from tank 50 is circulated in parallel through the cathode compartments by means of pump 48. A membrane leaf described Fig. 2 (not shown) comprises a rectangular frame supporting a membrane positioned between fine mesh protective cloths and then between open mesh cloths, e.g. of polypropylene. The apparatus may be used in the production of quaternary ammonium hydroxide e.g. the production of tetraethylammonium hydroxide from tetraethyl-ammonium chloride; e.g. using stainless steel cathodes and graphite anodes. The cloth between the membrane and the graphite anode may be of finely woven glass cloth, and serves to protect the membrane from abrasive particles of graphite eroded from the anode. The protective cloth between the membrane and the cathode serves to contain ion exchange resin particles which have disintegrated from the membrane. The pressure in the anode compartment may be higher than in the cathode compartment to prevent osmotic diffusion of water through the membrane.
